  Copying device, in particular for making film copies.



   The invention relates to a device intended for copying film tapes, in which the negative tape is guided in the form of a loop over a cylinder which receives the light source.



   The essence of the invention is that the cylinder is provided with a plurality of light transmission slits. An unexposed photo tape, which is fed through a guide, is pressed against each of these slots by means of a pressure piece. In this way, copies are made on all positive films while the negative film is passing by.
 EMI1.1
 
The drawing illustrates an embodiment. a denotes the negative film that unwinds from roll A and leads in the form of a loop over the glass cylinder c, which receives the light source d and is equipped with light transmission slits s, in order to then reach the film take-up roll A '.
